Is there an app that locks the phone while my child studies?

Is there an app that locks the phone while my child studies? Yes. Name a Homework window for the nights and hours you pick and the phone goes quiet on its own, with the clock locked so it cannot be ended early.

Add the homework itself as a chore and the phone stays locked until it is checked off and you approve. You can leave a music app or a calculator in the window's allowed list. A one-tap pause covers the night the test moved. Phone calls keep working, so a child who needs you can always call.

One price, unlimited children and devices. 7-day free trial, billed by Apple.

The short version

✓ Multiple downtime windows

Apple's Screen Time gives you one downtime a day. SimpleSentinel gives you as many named windows as you need per child, school hours and bedtime both, each on the days you pick, with a heads-up chime before each one starts.

✓ Scheduled chores that can lock the phone

Type a chore, pick a child, set when it's due, and decide what happens if it isn't done: their phone stays open, goes into downtime until it is done, or locks fully until it is done. Count it done on their check-off or only on your approval.

✓ The clock is locked

A child's phone keeps network time from the moment it's linked, so there's no changing the time to end downtime early or skip a chore. Screen Time has no such lock; SimpleSentinel does, on every child's phone, all the time.

What still works during a lock

Calls to and from you keep working. Apple keeps the Phone app reachable no matter what. Your emergency alarm and a No Ignore message still reach the screen. A pause stays until you lift it, through restarts and through a scheduled downtime window. SimpleSentinel never reads what your child types, watches or browses.
